Disclosed is a process for regenerating a used HX alkylation catalyst, wherein X is a halogen, by removing acid soluble oil, produced as an undesirable by-product of the alkylation reaction, from a liquid containing a sulfone compound. The process includes the use of water to induce the formation of the two immiscible liquid phases of ASO and sulfone with water. The two immiscible phases can subsequently be separated from each other. <IMAGE> |
